This Study established a methodology to automatically recognize and investigate the cadastral control point by utilizing beacon among the Internet of Things and developed an experiment system to evaluate the applicability of such methodology. In addition, by evaluating the technicality, economic feasibility, and effectiveness of the realized system by experimentally producing the actual beacon control point, this Study sought to propose the applicability in the investigation and management sector of cadastral control points in the future. The results of the Study are as follows.

The Study examined the general contents of the cadastral control point and Internet of Things and reviewed the current status of the management of cadastral control points and the technical application of Internet of Things. The Study deducted the issues regarding systematic management over cadastral control points pursuant to the reviewed results and the necessity of introducing new technologies to resolve such problems. The introducing methodology for the IoT beacon technology was established based on necessity. Based on the established methodology, a cadastral control point investigation and experiment system was designed and realized.

An experiment area was selected to evaluate the technicality, economic feasibility, and effectiveness of the control point investigation system that was realized for the experiment. The experiment areas were selected as the Multi functional Administrative City District of Sejong-si and Okgil District of Bucheon-si, Gyeonggi-do. A beacon control point was installed underground at the research areas for the experiment. A total of six were installed underground, three at the Okgil District of Bucheon-si and three at the Multifunctional Administrative City District of Sejong-si.

The results of evaluating the technicality of the system showed that, in the evaluation over the signal strength pursuant to the restricting conditions per distance, the signal strength appeared to be strong with an average of 19.7dBm at a 3m distance for Okgil District at Bucheon, but relatively weaker with an average of 9.7dBm at a 5m distance. In the Multifunctional Administrative City District of Sejong-si, the signal strength appeared to be strong with an average of 22.7dBm in a 3m distance, but relatively weaker with an average of 14.3dBm at a 5m distance.

The results of comparing with general beacon products showed the beacon produced for this Study to be generally more superior in terms of performance compared to general beacons. In the evaluation over economic feasibility, a benefit of KRW 2,975,964,000 appeared to be occurring every year. A net benefit of KRW 2.7 billion could be predicted for the year of 2045which is after 30 years, as a result of predicting based on 2015, thus, the current net value could be confirmed. In addition, the cost-benefit ratio and internal return ratio respectively appeared to be 1.068 and 7.08%, showing the validity of application.

In the evaluation over the effectiveness, when investigating based on the cadastral control point by using the realized system, the preparing process did not appear to be necessary because the preparing and organizing process could be processed through computer at the field regarding the detailed processes of existing field investigations, and as a consequence, it appeared that the existing six processes could be reduced to four processes. Moreover, in terms of the number of people needed for the investigation, it appeared that one person was sufficient to handle the investigation based on the realized system, thus, it appeared that the manpower could be reduced to one person.

The manpower required for the current cadastral control point investigation could be reduced and the time required for a field investigator to find a cadastral control point could be reduced when using the beacon technology, thus, the overall time for investigating a control point may be decreased. In addition, management on the cadastral control point may be converted to a computerized management system, which will make available the monitoring over management condition of the control points of the entire national territory by computer.

Lastly, this Study suggested the possibility of cadastral control point investigations by using the beacon technology among Internet of Things over a total of six supplementary cadastral control points as an experiment. Thus, for the cadastral control point investigation method using the beacon system to be commercialized and utilized, future studies will have analyze a higher number of control points, and preparation of institutional specific improvement plans will be needed in the cadastral surveying fee issue or related laws and regulations. 본 연구에서는 사물인터넷 중 비콘 기술을 활용하여 지적기준점을 자동으로 인식‧조사할 수 있는 방법론을 정립하고 이의 적용 가능성을 평가해 보고자 실험 시스템을 개발하였다.
